| Definition | A marine seismic source where a pair of conventional airguns (one, the generator, fires in the conventional manner; the second, known as the injector) fires some milliseconds later to prevent bubble from collapsing. Could be used in true GI mode (volume of injector twice of volume of generator), harmonic mode (same volume of generator and injector) or true airgun (no delay between generator and injector). | ||
